2000 220CDI - EGR / Vacuum
Hello! 
So I have this issue with my car, the idle is hunting when cold, and with some RPM there is alot of black smoke. When the engine is 80C there is loss of power/hesitation and black smoke.
The thing is, when I block the vacuum to the EGR (before vacuum regulator) the issues goes away, and it runs with no problems. No bad idling, o black smoke, and no loss of power.
EGR and manifold was cleaned, swirl flaps was OK, there was some play but not much.
Can't find any vacuum or boost leaks. And there is no codes.
I'm out of ideas
New / Used (34000km) EGR
New MAF sensor
New MAP sensor
New vacuum regulator (EGR)

Might want to try posting in the diesel section too. Most people in this section have gas cars.
